Reading Ages From Elephant Teeth Stuns Scientists
The article describes Professor Henry Fairfield Osborn's claim that elephants teeth enamel length can indicate age and evolutionary timeline. It explains how molars wear forward as new teeth form, compares modern and ancient elephant teeth, and links enamel length to a geological clock for dating fossils. It notes a 39.5 inch enamel length for Archidiskodon from the Late Pliocene.

Dawn Man Oldest Human Claim Backed By Enamel Study
Teeth found with the Piltdown skulls align with Dawn Man as the oldest known human, says Osborn, arguing a million year antiquity. He uses enamel measurements from Palaeoxydon and later elephants to support a revised time scale placing Dawn Man at about 1,000,000 years and other ancient humans from 920,000 to 30,000–40,000 years.

Osborn's Bold Theory On Earliest Human Ancestors
The article discusses Professor Osborn's radical dating of the oldest specimens from Dawn Man to Java Ape Man, noting mixed reception and anticipated scholarly questions. It highlights his elephant-focused expertise, potential dissent over linking Archidiskodon to Dawn Man, and the uncertain, poorly documented discovery of Dawn Man's skull fragments found by road workers.
